It calls the function float_expr to evaluate two values ,... (1 Reply)

kas_stringtokey
KAS_STRINGTOKEY(8) AFS Command Reference KAS_STRINGTOKEY(8)NAME
kas_stringtokey - Converts a character string into an octal key
SYNOPSIS
kas stringtokey -string <password string>
[-cell <cell name>] [-help]
kas str -s <password string> [-c <cell name>] [-h]
DESCRIPTION
The kas stringtokey command converts the character string specified with the -string argument into an octal string suitable for use as an
encryption key.
The kas command interpreter generates the octal key by using an encryption algorithm on the combination of the specified string and the
name of the local cell (as recorded in the local /etc/openafs/ThisCell file). Use the -cell argument to convert a string into a key
appropriate for a cell other than the local one.
CAUTIONS
This command writes the key to the standard output stream, on which it can possibly be intercepted by third parties. It is not very secure
to use the key in an actual Authentication Database entry.
OPTIONS -string <password string>
Specifies the character string to convert into an octal key.
-cell <cell name>
Specifies the complete Internet domain name of the cell to combine with the password string while generating the key. If this argument
is omitted, the kas command interpreter determines the name of the local cell by consulting:
o First, the value of the environment variable AFSCELL.
o Second, the cellname in the /etc/openafs/ThisCell file on the local machine.
-help
Prints the online help for this command. All other valid options are ignored.
OUTPUT
The output is of the following form:
Converting I<password string> in realm 'I<cell_name>' yields key='I<key>'.
EXAMPLES
The following example shows the octal key equivalent of the string "new_pswd" in the ABC Corporation cell.
% kas stringtokey new_pswd
Converting new_pswd in realm 'ABC.COM' yields
key='346307364320263233342354'.
PRIVILEGE REQUIRED
None, and no password is required.
